is a carrier board for the VisionSOM-STM32MP1 family of computer-on-modules which are powered by STMicroelectronics STM32MP15x application processors (single or dual core ARM Cortex-A7 + internal microcontroller Cortex-M4). A carrier board, together with a System on Module (SoM), makes a complete development platform similar to SBC. The carrier board houses the most common interfaces such as debugger, USB, Ethernet, UART, etc. A large variety of interfaces allows to use it as both a complete development platform or as a stand-alone end-product.

== User Interface (switches and LEDs) ==
1. All I/O lines are 5V compatible.<br />
[[File:VisionCB-STM32MP1-STD-v11_user-led.png|center|700px]]
2. RESET line is 5V compatible.<br />
3. Preferred voltage range on AIN0…AIN3 lines is 0…+3.3V.<br />
4. Voltage level compatibility can be changed using jumper selector (V-ARD), but voltage range on AIN0…AIN3 lines must be 0…+3.3V.<br />

VisionCB-STM32MP1-STD v.1.1 Datasheet and Pinout

General description

VisionCB-STM32MP1-STD is a carrier board for the VisionSOM-STM32MP1 family of computer-on-modules which are powered by STMicroelectronics STM32MP15x application processors (single or dual core ARM Cortex-A7 + internal microcontroller Cortex-M4). A carrier board, together with a System on Module (SoM), makes a complete development platform similar to SBC. The carrier board houses the most common interfaces such as debugger, USB, Ethernet, UART, etc. A large variety of interfaces allows to use it as both a complete development platform or as a stand-alone end-product.

The carrier board connects with the SoM via a standard SODIMM200 connector. VisionCB-STM32MP1-STD is equippped with internal ST-Link/v2-1 debugger with SWD interface and serial USB console port.
